When I jailbroke my iPod touch, I could use the app Cydia to install small tweaks like changing fonts, changing the color of menus, and making the title of the song playing appear in the bar at the top of the screen. When I got my Droid, I was expecting to find little tweaks like these all over the marketplace, but it seems things like this requires downloading home replacement apps or installing custom roms. Is there like a marketplace alternative full of tweaks? For instance, if I wanted more homescreens, I could just go into this alternative marketplace and install a tweak to add more homescreens. Am I just missing something or what?
